Chromecast Grey Screen (Causes and How to Fix)

Chromecast is excellent when it comes to delivering a great streaming experience. You can watch from various streaming platforms and even cast your own screen onto an Android or Google TV.

However, much like any other system, it can still run into a handful of problems. One of the more frequent ones is when your TV doesn’t register a playback, and the screen becomes grey.

A Chromecast grey screen can happen because of faulty connections, a firmware issue, or a casting issue. They’re annoying but easy to fix, as you’ll find out in our handy guide.

If you want to learn more about Chromecast grey screen causes and how to fix them, you’ve come to the right place!

Causes of Chromecast Grey Screen

When your TV suddenly goes grey while using Chromecast, it’s either an external or internal issue.

Faulty Connection

Cable connections are crucial for smooth streaming. Even something as simple as a twisted cable can result in various problems, including a grey screen.

Since Chromecast connects to Android TVs through a short cable, it’s highly likely to become loose over time. Aside from that, an unused HDMI port can also accumulate debris, resulting in a faulty connection.

So, if you encounter a grey screen when using your Chromecast, start by checking out all the cable connections first.

Outdated Firmware

Like many software, updates are necessary to keep the device operating more efficiently. However, you can also run into some problems when it comes to recent updates.

Chromecast uses Over the Air (OTA) updates. This advanced technology lets you update the device’s software via an internet connection.

Although this is super convenient, there’s a high probability that any minor bugs within the code that ruin the streaming experience, which is precisely the case for Chromecast.

Casting Issue 

A grey screen can also mean there’s a casting issue. Casting is when you mirror your screen to your Android or Google TV via Chromecast. Sometimes, the casting isn’t successful, leading to incomplete video playback or none at all.

To do this, you connect your device to the same Wi-Fi network as your TV. If they’re running on two different networks, the TV won’t pick up the device, and you’ll get a grey screen.

If casting still fails, then the problem could be a poor internet connection. You should also check if you’re using Chrome’s latest version since outdated versions can also interfere with the casting process.

How to Fix Chromecast Grey Screen

Luckily, there are a couple of simple ways to fix your Chromecast problems.

Update Chromecast

The first troubleshooting option is to update Chromecast. You can do this either do it automatically or manually.

The first time you set up Chromecast already prompts an automatic update. However, some versions may reach other softwares later, which delays some of the updates.

To check whether Chromecast has the latest version, follow these easy steps:

  1. First, check the latest firmware version of your Chromecast.
  2. Make sure that your device and Chromecast are on the same internet connection.
  3. Next, open the Google Home application and look for your Chromecast device.
  4. Then, open the device settings by clicking on the gear icon.
  5. Scroll down until you see which version is on your device. If it’s the same as the one on the App Store, then your device is up-to-date.
  6. However, if they’re different, go back to the device settings and click on the three dots.
  7. From the pop-up window, click on Reboot. This process will shut Chromecast off and install the latest firmware.
  8. Finally, check whether the newly installed firmware is the newest version.

Reboot the Chromecast

Often, an easy solution is to simply restart your Chromecast device.

  • To do this, open the Google Home App, Touch and hold the device’s title, tap settings, more settings then reboot.
  • Alternatively, you can simply unplug the Chromecast for at least 60 seconds which will reboot the Chromecast.

Change Resolution

You can also change the TV’s resolution to match the Chromecast’s output. Typically, this process is automatic, but here’s how you can do it manually:

  1. From your TV, select Settings.
  2. Go to Display and Sounds.
  3. Choose Advanced Display Settings.
  4. Then, click on Resolution.
  5. Finally, choose the most compatible resolution for your device.

Clear the cache

It would also help to try clearing the cache of your Chromecast.

To clear the cache on Chromecast with Google TV, you need to follow these simple steps:

  1. Go to your profile icon and select Settings, then System, then Storage, then Internal shared, storage then Cached data. Select “Clear cached data for all apps,” then click Ok

Power the Chromecast from the socket

If you are currently powering your Chromecast through the USB port on your TV, it might be the case that the Chromecast is not receiving enough power. To fix this, power the Chromecast through the mains socket instead.
